IMPROVED BIRD-CAGE.

To all whom it may concern:

Be it known that I, CHARLES L. OsnoRN, of Brooklyn, county of Kings, andState of New York, have invented new and useful Improvements inBird-Cages; and I hereby declare that the following is a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, making a part vof this specification, and the letters ofreference marked thereon, in which the same letter represents the samething in each figure.

Figure l is a top view of the base of my improved cage; Fig. 2, a frontelevation thereof; Fig. 3, a cross-section of the top piece; Fig. 4, across-section of the under cap of the top piece and ring; Fig. 5, a.detaceed view of the opening for the feed-cups; Fig. 6, the same, witha cross-section of the feed-cups in place; Fig. 7, a top view of thefeed-cups; Fig. 8, a top view ofthe improved perch.

A represents the base; B, the curved rest thereon; C, the cage; D, thebottom rim; E E, steel lips thathold rim D securely to curved rest B5 F,the hook that fastens rim D when in place beneath lips E E 5 G, the toppiece to support the cage; H, the under cap that secures the top pieceto the cage and sustains swing K5 I, the male screw to connect cap Hwith top piece, G5 J, the female part of the same; L, thereceiving-post, having a socket for post M of feed-cup R; N, a spiralspring in supporting-post Q 5 O, the cap above the spring 5 P P, shortbars over theUi'eed-cups 5 S, the outwardly-curved side of the feed-cup5 T, the perch; U, the tapering arms of perch 'l 5 V, the door 5 W, thebar beneath it.

The operation is brieiiy as follows: Insert screw I from inside the cageinto its corresponding part, J', in top piece, G, and turn it` home;place rim D beneath the hard-steel lips E E, bringing it snugly againstcurved rest B on base A 5 turn up hook F over bar W, beneath door V5pass the lip of the feedcup beneath short bars P P5 insert the part ofpost M beneath the cup into the socket of supporting-post Q5 pressdownward upon cap O and spring N sufficiently to pass the upper end ofpost M into the socket of receivingpost L, and spring N will secure thecup in position.

The advantages of a cage of this construe tion are First. Itis wellknown that vermin leave birds in the morning and seek shelter increvises of the cage. M y cage is entirely of metal, and there is nocrevice in which to hide. .Therefore it is a perfect protection againstthe pest of bird-lice.

Second. The adjustment of the cage to the base by the rim, curvedrest,t\vo steel lips, and a single hook is secure, neat, and handy,admitting ofinstantaneous removal, and holding the cage tight in itsplace.

Third. The manner of securing the cage to the supporting top pieceleaves no crevices, and is of simple arrangement.

Fourth. The mode of securing the feedcups and arranging the wires andposts thereab ut makes it impossible for the bird to escape when thecups are removed.

Fifth. It is found that the feet of confined birds lose the power tograsp, so that when removed to other cages they fall from the perches.The cause is non-user, as human beings, from lack of exercise, lose theuse of their limbs. By making the perch of varying size the muscles ofthe feet of the bird are constantly exercised in different degrees andtheir natural force retained. The projecting arms of the perch conduceto evolutions pleasing to the bird and the beholder.

An objection with many to keeping birdsis, the dirt arising from theirwasteful habits of throwing seed outside the cage. By makingthefeed-cups extend outwardly near their base the seed is caught by theinward curve above and drops back.

What I claim, and desire tosecure by Letters Patent, is-

l. The combination of curved rest B, rim D, lip E, and hook F, or theirequivalents, 0perating together to secure a cage to its base.

2. The arrangement described, by which the feed-cups are inserted andsecured without danger ofthe escape of the bird when removed.
